Definitions
- the present invention relates to antimicrobial compositions. It finds particular application in conjunction with automated sterilizing or disinfecting of medical instruments and will be described with particular reference thereto. However, it is to be appreciated that the present invention will find utility in sterilizing and disinfecting a wide range of objects, either automatically or manually.
- Liquid sterilization systems were utilized for equipment which could not withstand either the autoclave or the ethylene oxide.
- the equipment was immersed in a vat or tank that had been filled with a sterilizing solution, such as stabilized hydrogen peroxide or glutaraldehyde. Because such liquid sterilizations were normally performed manually, the skill and care of the technician were controlling factors in whether sterilization or disinfection were, in fact, attained. In many instances, the technician was required to mix the components of the anti-microbial composition. Even when mixed properly, relatively long immersion times on the order of six to ten hours were commonly required to assure sterilization. Moreover, many liquid sterilization systems were highly corrosive to metal parts, particularly brass, copper, and aluminum. With long immersion times, even carbon steel and stainless steel could be pitted and sharp cutting edges dulled.
- an anti-microbial solution which comprises an oxidizing anti-microbial agent, a copper and brass corrosion inhibiter, an aluminum corrosion inhibitor, a steel corrosion inhibitor and buffering agent, and a wetting agent. If tap water is used as a dilutant, a sequestering agent is also provided.
- the oxidizing anti-microbial agent is selected from the class consisting of ozone, peracetic acid, organic peroxides, hydrogen peroxides, inorganic peroxides, and other oxygen releasing compounds, chlorine, chlorine dioxide, active chlorine releasing compounds, such as chloramines, hypochlorites, and phenol.
- Peracetic acid in a range of .005-1.0% is preferred.
- the copper and brass corrosion inhibitor is selected from the class consisting essentially of triazoles, azoles, benzoates, and five membered ring compounds. Triazoles, particularly benzotriazole and tolytriazole, are preferred.
- the aluminum and steel corrosion inhibitor and the buffering agent were selected from the class consisting essentially of chromates, dichromates, borates, phosphates, molybdates, vanadates, and tungstates. More specifically to the preferred embodiment, phosphates are preferred for inhibiting steel corrosion and buffering the solution to a substantial pH. Molybdates are preferred for inhibiting aluminum corrosion.
- a method of sterilizing medical instruments is provided.
- Powdered water soluble reagents including a copper and brass corrosion inhibitor, an anti-corrosive buffering agent, a sequestering agent, and a wetting agent are dissolved in water and circulated through the plumbing of an automated sterilizing apparatus and over the medical instruments to be sterilized.
- a concentrated, oxidizing anti-microbial agent is diluted into the water with dissolved powder reagents and circulated through the plumbing of the automated apparatus and over the medical instruments. After the diluted anti-microbial has remained in contact with the medical instrument for a selected duration, the anti-microbial solution is drained and the medical instrument is rinsed with sterilized water.
- the reagents are selected from the classes discussed above.
- One advantage of the present invention is that it provides an anti-microbial agent which quickly sterilizes or disinfects medical equipment or the like.
- Another advantage of the present invention is that it works on substantially all materials with minimal corrosion.
- Yet another advantage of the present invention is that it facilitates automated sterilizing and minimizes operator error.
- a dilutant or water source 10 supplies water or other fluid reagents.
- the water source includes a length of tubing 12 connected with a water spigot or other building plumbing and a control valve 14 for selectively preventing and permitting the flow of water to a sterilizing means 16 .
- the sterilizing means is a filter which removes particles which are as large or larger than bacteria.
- an in-line water treatment means may be provided for modifying the chemical composition of the water.
- a water softening cartridge may be provided for reducing or eliminating calcium and magnesium salts from the water.
- various water treatments may be added to the water, such as a wetting agent, a sequestering agent, or others of the reagents to be discussed herein below.
- a tubing system 18 connects the filter or sterilizing means with a container or module 20 for receiving an item to be sterilized.
- the container is defined by a removable tray 22 configured in accordance with the item, e.g. an endoscope.
- a lid 24 is sealed to the tray in a lowered position by a resilient gasket 26 to complete the container.
- a transparent window 28 is defined in the lid.
- the tubing system includes a spray nozzle 30 and a container distribution manifold 32 for distributing water and other fluids around the item to be sterilized.
- a reagent receiving well 34 collects the fluid for return.
- Vent lines 36 enable air to be vented from the container such that it is completely filled with the water or other sterilant solution. Any excess fluid is discharged through check valve 38 into a drain line 40 .
- a reagent introduction system 42 introduces corrosion inhibitors and anti-microbial agents into the water.
- the corrosion inhibitors are introduced first and circulated over the item to be sterilized or disinfected before the antimicrobial agent. This provides corrosion protection before the corrosive anti-microbial agent contacts the item.
- the corrosion inhibitors and anti-microbial agent may be introduced concurrently such that both reach the item contemporaneously.
- An aspirator 44 which draws a oxidizing sterilant concentrate or other liquids from an ampule 46 .
- the oxidant is concentrated peracetic acid which has a stable shelf life of several months.
- the operator opens a container having a premeasured dose of powdered reagents and the liquid filled ampule.
- the powdered reagents are emptied into the well 34 and the ampules positioned to be pierced and drained by the aspirator.
- the powdered reagents include a buffer, e.g. a phosphate, for bringing the pH to a neutral level and to inhibit steel corrosion.
- a wetting agent further inhibits pitting of metals.
- An aluminum corrosion inhibitor such as a molybdate inhibits aluminum and steel corrosion.
- a copper and brass corrosion inhibitor preferably a triazole, protects copper and brass components.
- phosphates, molybdates, triazoles, and wetting agent interact to protect steel, aluminum, copper, and brass better than if any one were eliminated.
- a sequestering agent e.g. sodium hexametaphosphate, is included to prevent the precipitation of its calcium and magnesium salts.
- a pump 50 selectively draws water from the container 20 through well 34 and aspirator 44 . Recirculating the water dissolves the powdered reagents and aspirates the sterilant from the ampule and circulates the sterilant and reagents through the tubing system 18 .
- the vent line 36 is very short and of a substantial diameter such that the solution is circulated over exposed surfaces of the drain check valve 38 and a vent check valve 52 .
- a heating coil adjusts the temperature of the solution. Recirculation continues until the interior of the container and all exposed surfaces of the tubing system and valves are sterilized. Alternately, once fully dissolved, the sterilant may remain quiescent for a selected duration.
- the sterilant solution is drained through a drain valve 56 and sterile air is drawn into the system through an air sterilizing means - preferably a filter that removes any particles the size of a bacteria or larger.
- an air sterilizing means - preferably a filter that removes any particles the size of a bacteria or larger.
- the filled valve 14 is opened and the drain valve 56 is closed such that the sterile filter 16 provides a source of sterile rinse.
- the sterile rinse passes only along sterilized surfaces of the tubing system and valves in order to assure sterility. Every tubing and valve surface from the filter to the drain was exposed to the circulating sterilant solution for a sufficient duration to assure its sterility.
- the pump 50 circulates the sterile rinse through the system for a selected duration sufficient to rinse salt residue that the buffered strong oxidant tends to deposit. At the end of the rinse cycle, the rinse solution is drained by opening drain valve 56 . When a return valve 60 is closed, the pump 50 functions to pump liquid from the system out the drain 40 . Additional drain lines (not shown) and aspirators or pumps (not shown) may be provided for removing liquids from every region of the system. The exact location of such additional drains will be dependent on the bends and contours of the plumbing system.
- the ampule contains 35% peracetic acid and appropriate stabilizers, as are known in the art to provide an acceptable shelf life.
- the volume of the ampule relative to the volume of the tubing system 18 is selected such that the peracetic acid is diluted to about 0.2% by weight per volume solution. However, final solutions of .005 - 1% may prove acceptable.
- Other oxidants may also function suitably as an anti-microbial such as phenol, ozone, organic peroxides, hydrogen peroxides, inorganic peroxides and other active oxygen releasing compounds, other oxidants such as chlorine dioxide, chlorine, hypochlorites and active chlorine releasing compounds, such as chloramines.
- the selected anti-microbial, and its concentration, and the contact time with the item will vary depending on whether disinfection or sterilization is sought. In many applications, only disinfection is sought. The contact time or the strength composition of the anti-microbial agent may be adjusted accordingly.
- the copper and brass corrosion inhibitors are preferably benzotriazoles and tolytriazoles, which are preferred due to their stability in the presence of strong oxidizing compounds.
- Mercaptobenzathiozol might also be utilized but is more apt to be oxidized or destabilized by strong oxidizers.
- Azoles, benzoates, and other five membered ring compounds may also prove acceptable as copper and brass corrosion inhibitors.
- the anti-corrosive buffering compounds are preferably a mixture of phosphate in sufficient volume to produce a final concentration of 1.25% weight per volume and molybdates in an appropriate amount to produce a final solution of .011% weight per volume.
- Phosphates may also be effective in the range of 0.2% to 12% and the molybdates may be effective from 0.1 to 10%.
- borates, chromates, dichromates, tungstates, vanadates and combinations thereof may be substituted in appropriate concentrations to inhibit steel corrosion, i.e. buffer to a generally neutral pH, and aluminum corrosion.
- a sequestering agent appropriate to prevent precipitation such as sodium hexametaphosphate, may be provided.
- the sequestering agent may be eliminated. However, to insure universal applicability with any water that might be utilized, the presence of a sequestering agent is preferred.
- a wetting agent present to about 0.001 percent (W/V) improves the wetting of the surface of the instrument by the anti-microbial agent.
- the wetting agent has also been found to increase penetration of the anti-microbials improving anti-microbial efficacy while reducing corrosion.
